High service performance combined with High Availability

Extracting the highest possible performance in events processing or in any distributed computing systems for that matter can be achieved only if we can leverage data caching. A new layer called data grid as a distributed in-memory processing fabric must be established around most I/O and processor-consuming frameworks and service resources, primarily around ESB and databases. Regarding service resources and DB in particular, the clustering technique has been around for quite a long time; therefore, we doubt that your mission-critical DBs are not installed on RAC using SAN and so we will not dwell into it.

To serve HA and high-performance purposes, this fabric must satisfy certain criteria:

  • Data Grid/fabric partitioning around a resource-consuming framework must be dynamic and automatic; that is, you should be able to add new servers into the cluster, automatically change the partition, and consequently, data replication and the processing...
